The actual tour was nice and the gentleman (captain)doing the speaking was excellent. A female did the second half of the tour and was not as polished as the gentleman in her delivery of the information. They were short staffed with regards to filling food orders, so there was an extremely long wait and our group wasn't able to eat at the same time. I felt sorry for the lady taking orders, and running back and forth in an attempt to deliver the food. She was not the cause of the problem, was apologetic for the long waits, and did her best to make things right. We will most likely take guests on the tours in the future as it was informative and pleasant. We will possibly avoid having a "meal" and maybe stick to a beverage only.
